1986 Map of Signal Hill

About this map

Cedar Valley and the southwestern edge of Austin meet along the ridge lines of central Texas in this 1986 revision. The landscape is defined by the headwaters of numerous waterways, including Williamson Creek, Slaughter Creek, and Bear Creek, which carve through the limestone terrain toward the southeast. The map documents the rural-to-suburban transition as the Austin corporate boundary pushes into former ranch lands, yet several historic markers remain. Genealogists and local historians will find the Oliver Cem and Johnson Cem preserved amidst the hills, along with community focal points like Friendship Ch and the Boys Camp near Friday Mountain. From the elevated Signal Hill Radio Tower to the small pockets of resource extraction at various Gravel Pits, the map captures the region's topographical complexity and shifting land use patterns during the mid-1980s.
